Iceman is a Marvel Comics character who is a superhero and a founding member of the X-Men along with Cyclops and Beast. He has the ability to manipulate ice and cold by freezing water vapor around him. This allows him to freeze objects, as well as turn his body into ice.
The X-Men arrive in the Blackbird: Iceman, Storm, and Colossus, as well as the DISK containing Beast. After Beast is attached to Jessica's wristband, he explains how it is possible to use Cerebro and the energy from Ōkuma's teleporter to follow him to Loki.
